Abstract

Deux éléments de moule (16, 17), qui forment chaque corps de moule métallique (15), sont fixés par l'intermédiaire de leurs axes de guidage porteurs respectifs (24, 25), de telle sorte que les éléments du moule peuvent être déplacés dans la direction axiale d'un corps tubulaire, et des plaques de serrage (18) sont montées dans les deux parties latérales des éléments partiels combinés du moule (16, 17), de telle sorte que tous sont fixés individuellement les uns aux autres. Les plaques de serrage (18) sont portées par des axes de guidage (22), ce qui permet de les déplacer dans la direction axiale du corps tubulaire, et chaque corps (15) de moule métallique est déplacé tout en étant maintenu à angle droit, par rapport à cette direction, par les plaques de serrage (18). Chacun des deux éléments d'un moule (16, 17) et chaque plaque de serrage (18) déplace les axes de guidage (22, 24, 25), qui supportent chacun d'eux, dans la direction perpendiculaire à l'axe tubulaire, et chaque unité peut alors, librement, être combinée à une autre et en être séparée.
